Moysent Simon

Moysent Simon was a French assassin who, in 1557, was hired by Catherine de Medici to assassinate her stepson Sebastian de Poitiers, who was serving as regent of France during the absence of King Henry II of France in Rome. Simon attempted to approach Sebastian's throne provide a "blessing" to him during his regency, but his guard Alec succeeded in restraining her before she could draw a poisoned dagger from her sleeve.
